In SQL, a procedure, also known as a stored procedure, is a collection of SQL statements grouped together under a specific name. This allows you to save and reuse the code easily whenever needed.  

Here are some key benefits of using stored procedures:


If you have a complex SQL query that you use frequently, you can store it as a procedure and call it by name instead of rewriting the entire query each time. This saves time and effort.


Procedures break down complex tasks into smaller, more manageable units. This makes your code easier to understand, maintain, and modify.


You can control access to stored procedures by assigning permissions to users. This helps to ensure that only authorized users can execute certain procedures.

Input Validation: 

Stored procedures can accept parameters, which allows you to validate user input before it is used in the SQL statements. This helps to prevent errors and malicious attacks.

Here's a simplified example:

Imagine you have a database table storing customer information. You frequently need to retrieve a list of customers from a specific country. Instead of writing the same SELECT query every time, you can create a stored procedure that takes the country name as a parameter and returns the matching customer records.

Overall, stored procedures are a powerful feature in SQL that can improve the efficiency, security, and maintainability of your database applications.
